country – optional – if the unit is part of the armed forces of a sovereign state, the name of that state.

allegiance – optional – used to indicate the allegiance of units which are not part of the regular armed forces of a sovereign state; can usually be omitted otherwise. In the case of National Guard or Naval Militia units, the State of origin should be indicated.

command_structure – optional – the larger unit(s) of which the unit is a part. This should not be used to provide an exhaustive history of the unit, which is more appropriate in the article itself, for units existing over a long period. For complicated cases, using the auxiliary command structure box may be appropriate.

garrison – optional – location of the unit's home base; this is generally applicable only to units in existence.

garrison_label – optional – the label to use for the garrison field (above).

nickname – optional – any commonly-used nicknames for the unit.

patron – optional – the patron the unit was named after; this is only applicable in armed forces where units are named after individuals.

colors_label – optional – the label to use for the colors field (above).

march – optional – the tune(s) commonly or officially played when the unit ceremonially marches; there may be several.

mascot – optional – any official or unofficial animal or character maintained by the unit.

equipment – optional – for units strongly associated with specific equipment or vehicles, such as tanks, artillery, or aircraft, a brief list of the notable types used by the unit; if the number of entries is large, it is recommended that this field not be used, and that the full list be given in the article text instead.

equipment_label – optional – the label to use for the equipment field (above).

battles – optional – any notable engagements in which the unit participated. The decision of what constitutes a notable engagement is left to the editors of the specific article.

battles_label – optional – the label to use for the battles field (above); this defaults to "Engagements" if left blank.

battle_honours – optional – for units in countries that award some type of formal battle honours, the battle honours that the unit has received; while this may have some overlap with the battles field above, the two are not necessarily equivalent.

disbanded – optional – for units that have been disbanded, the dates and any other relevant notes regarding the disbanding.

flying_hours – optional – if the formation is an aerial one, the total hours flown.

Commander parameters:

The infobox allows for up to three current commanders to be specified; the exact roles or titles of these individuals should be specified via the corresponding label parameters.

commander1 – optional – a current commander of the unit; this can be the acting commander, the ceremonial commander, the chief of staff, or any other leader.

commander1_label – optional – the label to use for the field above; for historical reasons, this defaults to "Current commander" if left blank.

commander2 – optional – a second current commander of the unit; this can be the acting commander, the ceremonial commander, the chief of staff, or any other leader.

commander2_label – optional – the label to use for the field above; for historical reasons, this defaults to "Ceremonial chief" if left blank.

commander3 – optional – a third current commander of the unit; this can be the acting commander, the ceremonial commander, the chief of staff, or any other leader.

commander3_label – optional – the label to use for the field above; for historical reasons, this defaults to "Colonel of the Regiment" if left blank.

notable_commanders – optional – any notable former commanders of the unit; judgement of notability is left to individual article editors.

Note that the various xyz_label fields above are intended for overriding the default labels on these fields as needed for particular countries or services; in most cases, however, the default value is sufficient, and the fields need not be included.

A command structure box may be used to summarize information about an individual military unit's parent and subordinate units; it should generally be used in conjunction with {{infobox military unit}}. If needed, multiple boxes may be used to show the unit's command structure during different periods.

Note: When using parameters, avoid the ambiguous abbreviation "N/A", and instead use "unknown" or "none". All subjective or qualitative judgements and numerical quantities or statistics must be cited to a reliable source (see WP:MILMOS#CITE).

name – the name of the unit or formation.

date – optional – the dates during which the given structure was in place.

A service record box may be used to summarize information about an individual military unit's or ship's service history; it should generally be used in conjunction with the appropriate primary infobox. If needed, multiple boxes may be used to separate the service record for different periods; for example, a unit that fought in several wars may have separate boxes for each.

The box should be added using the {{service record}} template, as shown below:
